Tests and recommendations. All the reviews focus on the usability of the tested equipment in the context of challenging unsupported expeditions. Thus, I focus mostly on their weight, durability, overall simplicity, dependability, and versatility.
I bought many of these items myself, for full (or nearly full) price. Various other items were received for free, for the purpose of testing (indicated in the text). In both cases, I always recommend each item only if it is worth recommending in the objective sense. Specifically, for any of these items, I always take them by choice of my expeditions (i.e., I do not actively seek better options, which I would do whenever I feel that an item performs suboptimally).
